Linear perturbations of self-gravitating spherically symmetric configurations
Eliana Chaverra, Néstor Ortiz, Olivier Sarbach
We present a new covariant, gauge-invariant formalism describing linear metric perturbation fields on any spherically symmetric background in general relativity. The advantage of t…
Schwarzschild black holes can wear scalar wigs
Juan Barranco, Argelia Bernal, Juan Carlos Degollado +5
We study the evolution of a massive scalar field surrounding a Schwarzschild black hole and find configurations that can survive for arbitrarily long times, provided the black hole…
Conformal diagrams for the gravitational collapse of a spherically symmetric dust cloud
Néstor Ortiz, Olivier Sarbach
We present an algorithm for the construction of conformal coordinates in the interior of a spherically symmetric, collapsing matter cloud in general relativity. This algorithm is b…
The propagation of particles and fields in wormhole geometries
Olivier Sarbach, Thomas Zannias
We discuss several properties of static, spherically symmetric wormholes with particular emphasis on the behavior of causal geodesics and the propagation of linear fields. We show…
